3. Sloths are capable swimmersTheir long arms and buoyant bodies allow them to move through water more effectively than their land speed might suggest.
4. They spend much of life hanging upside downSpecialized limbs, claws and anatomy make suspensory living energetically efficient.
5. Sloths descend to the ground infrequentlyMany species leave the canopy only occasionally, including for defecation.
6. Their low metabolism conserves energyA leaf-based diet provides limited calories, favoring slow movement and reduced energy expenditure.
